POWER-TRANSMISSION MECHANISM FOB MOTOB-VEHIOLES.

To all whom it may concern:

Be it known that we, EDWARD M. LOGAN and CLARENCE E. McNAUeH'roN,citizens of the United States, residing at Sonyea, in the county ofLivingston and State of New York, haveinvented a new and usefulImprovement in Power-Transmission Mechanisms for Motor-Vehicles, ofwhich the following is a specification.

This invention relates to power transmission apparatus for use withmotor propelled vehicles whereby the motor of the vehicle can beconveniently utilized for driving other machinery.

One object of the invention is to produce a practical and inexpensivetransmissionlapparatus of this kind which is of a construction adaptingit to be readily set up for use in any convenient place and which hasmeans whereby the motor vehicle can be readily driven by its own poweronto and retained in position thereon; also to provide simple anddesirable means for securing the vehicle on the apparatus and relievingthe transmission mechanism of a portion of the weight of the vehicle tothereby reduce the friction and wear on the same and on the vehicletires; also to provide vehicle stop and securing means which when notinuse are adapted to be moved to positions where they are out of the way;also to construct the apparatus so that it is adapted to be located in apit or space below a 'floor and covered by trap doors when not in use,so as to be out of'the way and not occupy floor space; and also toimprove apparatus of this sort in the particulars hereinafter describedand set forth in the claims.

In the accompanying drawings, consisting of three sheets: Figure 1 is aplan view of a power transmitting apparatus embodying the invention.Fig. 2 is a longitudinal sectional elevation thereof in line 2-2,Fig. 1. Fig. 3 is a fragmentary longitudinal sectional elevationthereof, on an enlarged scale, in line 33, Fig. 1. Fig. 4 is a rearelevation, partly .insectiomthereof, on a smaller scale than Fig. 3.Fig. 5 is a plan view showing the apparatus located in a pit beneathtrap doors, one of the jacks being shown in its inoperative positionthrough the open door. Fig. 6 is a sectional elevation -of the apparatusin the pit.

Like reference characters refer to like parts in the several figures.

suitable construction.

- Patented July 4, 1916.

A represents the supporting frame or base ofthe apparatus, which, asshown, is rectangular 1n' shape and composed of front and rear metalchannel bars a connected by sim- 1lar endbars a and intermediate bars a.The frame can, however, be of any B B represent pulleys which arejournaled in pairs at opposite sides of the frame A in posltion to formrolling supports for the rear or driving wheels of a motor veotherhicle. Preferably the pulleys are secured between the end andintermediate bars of the frame A on parallel shafts C C journaled insuitable bearings c on the frame and each pair of pulleys is preferablyconnected by a belt D on which the wheels of the motor veh1cle rest. Thebelts are adapted to bev off the pulleys due to the tendency of thetreads of the vehicle tires on the middle portions of the belts. Thepulleys are also preferably provided with end flanges between which thebelts are confined. The motion of the belts can be transmitted for anydesired purpose by a pulley E on the shaft C and a belt e, or by anyother suitable means.

The transmission mechanism as thus far described is constructed andoperates sub stantially like that disclosed in our co pendingapplication Serial No. 791,271, filed September 23, 1913.

F represents a way or track fen guiding the vehicle into position on thetransmission mechanism. As shown, this track is formed by horizontalgrooved rails f detachably secured to the frame A in line with thepulleys BB, and flanged inclines f connecting with the front ends of therails f. The inclines f preferably increase in width forwardly and thusfacilitate the guiding of the vehicle onto the rails f. The rear ends ofthe rails f are detachably secured on the frame A, for instance, by pinsf on the rails enterin holes in the frame and the edges ofthe beltstocurl up on account of j the pressure of the transversely convexedf ontends 0 the rails are similarly secured 11 gaging and lifting thevehicle.

on a cross connecting bar 7' by pins f. The inclines f are alsopreferably detachably connected to the front ends of the horizontalrails f by suitable means, such as pins f on the sides of the inclinesseated in sockets f on the sides of the rails 7, see Fig. 1.

By detachably securing the guide track in position and constructing itof detachably connected parts, as described, it can be readily placedinposition and removed so as to be out of the way and not occupyiloorspace when not in use. The disconnected parts by dotted lines in Fig. 2,when not in use.

A brace g, pivoted at its lower end to'th e frame A and adapted to haveits upper end removably seated in a socket in the bumper, holds thebumper in the upright position.

H H represent jacks or devices for securing the vehicle in place on thetransmission mechanism and relieving the traction belts D to a greateror less degree from the weight of the vehicle. Each jack has a frame Itof any suitable construction which is .suit-' ably hinged at its lowerend at k to the frame A so that it can be swung downwardly out of theway from its upright operativeposition, and a member k Which isvertically adjustable on the frame It for en- The lifting member h shownhas a head k suitably shaped to fit the rear axle of the vehicle and ascrewthreaded shank which passes through guides i i on the frame 72. andthrough the screwthreaded hole of a nut or wheel I which bears againstthe guide 2'. The head k preferably has a transverse vertical slot it.When used with a vehicle in which the axle has a truss rod, the trussrod is adapted to enter this slot h and permit the head to have a firmbearing against the rear axle casing. The jacks are releasably heldupright by suitable means, such as cross brace-rods K having hookedlower ends confined in holes in the frame A and hooked upper ends isadapted to be engaged in holes is in the upper ends of the jack framesIt. By unhooking the upper ends of thebrace rods and dropping them, thejacks can be swung downwardly toward each other from their uprightposition, as indicated in Figs. 5 and 6, so that they will be out of theway and will not interfere with the vehicle being. moved into positionon and 05 of the apparatus. After the vehicle is in position on theapparatus, the jacks are raised to the upright position beneath the rearaxle and secured. The lifting members 72. are then raised by turning thenuts or wheels I and the rear end of the vehicle lifted until its wheelsbear on the belts D only with suflicient pressure to give the requiredtraction. The jacks thus relieve the tires of the vehicle wheels and thebelts D of undue weight and Wear, and in addition they serve to preventthe'vehicle from shifting forwardly or rearwardly. on the apparatussince the vehicle axle is confined in the socketed heads of the jacks.The adjustable members of the jacks also enable them to be properlyengaged with the axle without lifting the vehicle, when this is desired.I

L L represent horizontal screws which pass through screwthreaded holesin lugs or parts Z on the heads of the jacks. By turning these screwsuntil they bear firmly against the brake disks 1 at the ends of thevehicle axle, the vehicle is securely held from shifting sidewise andworking off of the belts D.

This invention is not restricted to the described construction of thejacks, and jacks of other construction adapted to be moved to and fromthe operative position and to be operated to engage" or raise thevehicle can be used, and different means can also be employed forpreventing the vehicle from shifting sidewise on the belts D.

Instead of using the apparatus on the floor and providing the guide asdescribed. the frame A with the mechanism carried thereby can, ifdesired, be located in a pit or space beneath the floor and covered byone or more trap doors m. When thus located and the jacks are swungdownwardly from their upright positions, the trap doors can be closed,thus permitting the use of the floor above the apparatus. When theapparatus is used in a pit the bumpers G are not necessary and can beomitted if desired.
